Patent ZA-878825-B (ZA)
Title: Device conceived as nh3 reactor
IPC: C01C1/04
Filed: 1987-11-25
Abstract: In an NH3 reactor, especially with at least two heat exchangers concentrically arranged axially one after the other and catalysts beds surrounding these heat exchangers, it is intended by comparatively simple constructional means to provide optimum preheating and flow within the vessel for the circulating gas and/or process gas, while maintaining perfect cooling of the vessel wall, it being possible for the vessel in particular to have more than two catalyst beds. For this purpose, the inlet header (16) of the second heat exchanger (8) is fitted with a feed line (17), introduced radially from the side and/or from below, for at least a part of the circulating gas fed in the upper zone of the pressure vessel (2) and sweeping over the shell. <IMAGE>

Title: Apparatus for coating glass
Inventor: ALBACH EBERHARD R
IPC: C03B18/02
Filed: 1988-03-03
Abstract: A gas distributor beam includes a plenum and distribution slot surrounded by a generally V-shaped cooling fluid chamber. The circulation of a suitable cooling fluid tends to maintain the plenum and distribution slot at a temperature below four hundred degrees Fahrenheit for the distribution of diborane gas to an upper surface of a heated glass ribbon. Carbon blocks are utilized to stabilize the glass temperature above nine hundred fifty degrees Fahrenheit for the proper deposition of boron on the surface of the glass. Insulation between the carbon blocks and the outer walls of the cooling fluid chamber minimize heat transfer and the shape of the cooling chamber minimizes the exposure of the glass to the lower temperatures of the cooling chamber.

Inventor: SMEDLEY COLIN PETER
IPC: H04Q3/42
Filed: 1985-10-17
Granted: 1988-08-03
Abstract: The subscriber line signalling device (D) is employed in a digital telecommunications system. In particular the device (D) is used in a subscriber line interface module and it allows all signalling data to be detected and generated on a per-channel basis. A microprocessor (A) controls the device which generates and detects cyclically permutable code words on a plurality of traffic channel paths to or from the device. It is arranged that each generated cyclically permutable code word on any one traffic channel path is synchronously coded with respect to any other traffic channel path. The device can also be programmed to handle different data rates. In addition the operational modes of the traffic channels can be controlled giving loopback facilities allowing cyclically permutable code words to be generated and detected from the input and output traffic channels as desired and allow a diagnostic facility to be implemented.

Title: Coding security threads for bank notes and security papers
Inventor: JONES PHILIP BRIAN BRANT
IPC: B42D15/10
Filed: 1989-01-20
Granted: 1992-10-14
Abstract: A security thread (1) for a bank note comprises a discontinuous magnetic thread (3) which has binary coding, the binary values being denoted by the presence or absence of bit lengths of thread. The coding employed is repetitive, comprising alternating termination segments (4) and word segments (5). The length of a termination segment in terms of bit lengths is less than the length of a word but is greater than the maximum length permitted within a word of bits which have the same binary value as the bits in a termination segment. The invention provides resistance to false readings and, by varying the parameters of bit length, word length, length of the termination segment and otherwise, a multiplicity of different codings having the same general format.

Title: Glass bottle inspection machine
Inventor: EMERY MONTI D
IPC: G01M99/00
Filed: 1996-12-12
Granted: 1999-08-11
Abstract: A machine for inspecting a glass bottle comprising a bottle supporting track, a car for conveying a bottle along the track to a bottle inspection station. The car includes rollers for rotatably engaging one side of the bottle and a wall mechanism forcefully engages the other side of the bottle as it is conveyed to the bottle inspection station. The wall mechanism includes a pivotally displaceable support, which is biased towards a fully advanced position. Linear bumpers secured to the support extend into the path of a conveyed bottle when the support is at the fully advanced position so that a bottle will engage the linear bumpers and forcefully pivotally displace the support to a retracted position as the bottle is conveyed to the inspection station. The length of the linear bumpers is selected so that when a bottle is conveyed to the inspection station, the bottle will be conveyed past the linear bumpers whereby the support will be displaced back to the fully advanced position. When this occurs, rotating drive rollers on the support forcefully engage and rotate a bottle at the inspection station. The rotating bottle is then inspected.
